observability-and-instrumentation

SUMMARY

What it does

This Agent Skill provides guidance on instrumenting code to make production behavior observable and diagnosable. It covers structured logging, metrics (RED/USE), distributed tracing with OpenTelemetry, alerting on symptoms, and verifying telemetry. The skill is intended for developers adding logging, metrics, tracing, or alerting to features running in production. It is not for diagnosing ongoing failures (see debugging skill) or performance optimization.
